AUTOMATIC TIRE-UPSETTING- AND WIRE-TWISTING MACHINE.

To all whom it may concern:

Be it known that I, JULIUS W. PEPLINsKI, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Automatic Tire-Upsettingand Wire-Twisting Machines; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, forming part of this specification.

My invention relates to automatic tire upsetting and wire twistingmachines.

In the construction of baby carriage wheels and other like vehiclewheels upon which resilient tires are used,-the resilient tire isusually what is known as a cushion tire, with a'wire extendingthroughout the entire length thereof. This resilient material isconstructed in a continuous straight cord with a longitudinal holetherethrough, and is cut into the required lengths, and: wires insertedtherethrough of a len th sufficient to extend beyond the ends of tv eresilient tire material a proximately one and one half inches at eacend. The ends of this tire are then brought together, the resilient.material then pushed backward upon the 1 wire when the ends of the wireare twisted to- As it is difficult to push back or u gether. set theresilient material upon the wire su ciently so that when released itwill close completely over the splice in the wire, have i conceived thepresent invention and constructed a machine embodying the same intangible form, which machine is designed to automatically grip the endsof the wire,

push back or upset the resilient tire material Specification of LettersPatent.

Fig. 8 is a view in elevation of afragment of the drive-wheel end of my machine, looking in the directionof the ar-- row to in Fig. 1, the drive-wheel being broken off on theline ov in Fig. 1. Fig. 9 is a view in elevation of a cushion tire usedon a child s vehicle wheels. Fig. 10 shows the binding wire of a cushiontire gripped by the. wire gripping jaws of my machine, and the resilienttire material thereon pushed, or upset backward, and the Wire ready forthe twisting operation. Fig. 11 shows a fragment of a tire illustratingthe form of splice.

In these drawings A indicates the frame of the machine, which is adaptedto stand on a Upon the front of this frame A, I make suitable slide-Ways in which I place a slide B. In one end ofthis slide B, I make arecess 1), in which I inscrta spiral spring B of suitable resistance.-

an elongated opening a in the frame A.

There being a slide B placed in Ways a on each side of the middle of theframe A as shown in Fig. 1. Upon these slides B in suitable ways I)thereon I place jaw bearing slides O C the outer ends of which areprovided with inturned shoulders c c, and through these shoulders c c, Iplace regulating screws O O which are adapted to bear against thesprings B in the slides B, as shown in Fig. 5. It will be observed thatthe-slides O O are carried upon and by the slides B B, and that when theslides B B are moved apart from each other, any resistance tosimultaneous movement of the slides O CT therewith tends to compress thespring B (see Fig. 5) within the slides B, thereby forcing the slides OO to move from each other with a yielding pressure. Upon the inner endsof the slides O O, I secure stationary lower jaws D. and D, and abovethese stationary jaws D and D upon the slides O, I pivot the jaws D andD the said jaws-D and D being provided with levers at extending througha slotted opening a in the frame A as shown in Figs. 3 and 4. The leversd" are provided with regulating screws e by means of which the grippingforce of the jaws D and D can be regulated. The said jaws D and D (Fig.6) are provided with large transverse wire guiding grooves 11 adjacentto. the outer ends thereof, and with small transverse Wire v grippinggrooves d back of said Wire guiding grooves d, and the jaws D and D(Fig. 7) are provided with small transverse, wire gripping grooves (iadjacent to the front ends of said jaws, and. with large transverse Wireguiding grooves d backof said grooves d Upon the frame A between theends of the slides CC, and the jaws thereon, I secure a bracket E havinga socket in the top thereof adaptedtoreceive andsupport aslotted pinionF, sothat the slot f therein will be of the same elevation as theopening between the jaws DD and D D 5 For operating the foregoingdescribed "mechanism I provide the frame A with j ournal boxes A A and AA In the boxes A, I mount a main or drive shaft G. Upon this shaftG, Isecure a cam G adapted to-intermittently operate the jaw levers dsimultaneously, as hereinafter described. This cam G" is somewhatelongated in order that the levers (1 may slide spirally thereon. I alsoplace on the shaft G at each end of the cam G a cam wheel G having acam-groove 9 cut in the cylindrical" face thereof adapted to receive thestud B and to operate the slides B. B and C C" as hereinafter described.On one" end of the shaft G, I secure a wheel G having on its periphery asegment of gear teeth 9.

In the boxes A I mount a shaft II, having on one end thereof a gearwheel II, and on the frame A, I pivot a gear wheel H which intermesheswith the gear PI on the shaft H, and with the segment of gear-teeth onthe wheel G Upon the frame A, I secure a bracket J, and upon the bracketJ, I mount a spur gear J having secured to its side and concentrictherewith another spur gear K of slightly greater diameter. To drivethese gears J and K, I place upon the shaft H a spur-gear L whichintermeshes with the spur-gear J, and within. the socket in the bracketE, I. place a slotted pinion F, which intermeshes' with. the spur-gearK. Upon the shaft G, outside of the box A I place a collar N; againstthe collar N, I place a s ring N, and; against the spiral spring I Ipace a clutch sleeve N which is secured against rotation on the shaft Gby means of the ordinary spline and groove (not shown). Thissleeve isprovided with the usual clutch teeth; or notches n adapted to be engagedby like teeth or notches n on the hub of the drive-wheel .O. The clutchsleeve is also provided with a cam-shoulder N adapted to be engaged toopen the clutch and stop the machine. Upon the frame A, I secure abracket P, in: which I place a slide-belt or latch P which is held in aforward position, as shown in Fig. 1, by means of the spring 1), so asto engage the cam-shoulder N, and force the teeth on the sleeve h out ofengagement with the teeth on the hub of the drivewheel 0. For operatingthe slide or latch P, I provide a bell-crank-lever Q, which is pi votedupon the frame of the machine, with one arm in engagement with said boltP preferably by being inserted into a ring in the end of said bolt P.The other arm of the bell-crank-lever Q is connected with a foot lever(not shown) by means of a link R.

In operation a resilient tire S (see Fig. 9) of the required length isplaced upon a wire of sufficient length that the ends s and s extendsomewhat beyond the ends of the tire. The two ends 8 and s of the wireare then placed within the jaws D, D and. D D, so that the end 8 willextend. through the groove d in the jaws D D" and be gripped in thegroove d in the jaws D D, and the ends 8 of the wire will extend throughthe grooves d in the jaws D D and be gripped by the groove d in the jawsD D", with the ends of the resilient tire abutting against the outsideof said jaws as shown in Figs. 1 and 10. When in this position the endsof the wire pass through the slot f in the slotted pinion F, as shown inFig. 1. The operator then presses a foot lever (not shown) which causesthe bolt P to be withdrawn. to release the chuck sleeve N and allow thespring N to force the same into engagement with the teeth upon the hubof the drive-wheel, which causes the cam G to rotate and raise thelevers of the jaws D and D and cause said. jaws to firmly grip the tipends 8 and s of the wire. The cams then cause the slides C C to movehorizontally in their ways carrying with them the said jaws, the pair ofjaws D D drawing the end 8 of the wir through the jaws D D and the aws DD drawing the end 8 through the jaws D D to the position shown in Fig.10. When the slides and jaws have reached their fartherrnost traversethe cam-grooves g in the camwheels G will hold them stationary in thatposition while the segment of gear g on the Wheel G engages andintermeshes with the spur-wheel H which causes the wheels H and H andshaft H and spur-wheel L to retate, which in turn through the spur-gearsJ K, will rotate the slotted pinion F a sullicient number of turns tofirmly twist together the ends of the wire, embraced by the slottherein, and held by the jaws D D and D D. It will be noticed that thistwisting of the wire together tends to draw the said two pairs of jawstoward each other. It is here that the double slides B C and the springs13 within the slide B operate, by allowing enough yield to the slides CC to compensate for the shortening of said wire due to thetwisting'thereof. When the pinion F has been rotated a sufficient numberof turns to firmly twist the ends 8 and s of the wire together, thesegment of gear y will have passed out 'of engagement with the teeth onthe wheel H thereby permitting the slotted pinion to stop revolving withits slot in the position it was in before it. Was revolved. The cam Gthen releases the jaws D and D which permits the resilient tire to moveback over the splice as shown in Fig. 11, when the cam grooves g in thecam-wheels G causes the jaws to be returned to their inmost position,when the cam-shoulder on the clutch-sleeve N contacts with the bolt P aand causes the clutch to become disengaged and the machine to come to arest, at the end of one revolution of the main shaft G, ready foranother operation.

Having described the construction and operation of my machine so as toenable others to construct and use the same, I do not desire to limitmyself to the exact construction of mechanism shown and describedherein, as it is obvious that any one skilled in the art to which thisinvention appertains can readily embody the invention disclosed hereinin other forms of mechanism. Therefore What I claim as new and desire tosecure by Letters-Patent is:

1. The combination of two pairs of jaws, means for closing and openingsaid pairs of jaws, means for moving said pairs of jaws apart and towardeach other, means between said airs of jaws for twisting together wiresheld y said two pairs of jaws, and means for intermittently operatingsaid twisting mechanism, substantially as set forth.

2. The combination of a frame, slides therein, a pair of jaws on each ofsaid slides, a cam for opening and closing said jaws, cams for movingsaid slides away from and toward each other, a slotted gear wheelrotating in a socket in the frame between said pairs of jaws, means foroperating said cams, and

means for intermittently o erating said slotted gear wheel, substantialy as set forth.

3. The combination of two pairs of jaws, each having a transversegripping groove adapted to clamp a wire, and another groove which willallow a wire to slip therethrough, means for closing said pairs of jawsupon two parallel wires so one wire will be grip ed by one pair of jawsand the other wire y the other pair of jaws, means for moving said jawsaway from each other when the aws are closed and toward each other whenthe jaws are opened, a slotted twisting pinion mounted between saidpairs of jaws, means for rotating said pinion when the pairs of aws havebeen moved a art, means for intermittently opening and c osing saidpairs of jaws, and means for intermittently operating said twistingpinion, substantially as set forth.

4. The combination of a frame, slides thereon, two pairs of jaws, onepair mounted on each slide, each pair of said aws having a transversegripping groove ada ted to clamp a wire, and another slot whic willallow a wire to slide freely therethrough, cam mechanism for closingsaid pairs of jaws upon two parallel wires so one wire will be grippedby one air of jaws while the other wire will slide free y through thelarger groove in said jaws, and the other wire willbe gripped by theother pair of jaws, the first named wire passing through the largeropening therein, means for moving said pairs of jaws apart when closedso as to move said wires longitudinally one in each direction parallelto each other, a slotted pinion between said pairs of jaws, mounted androtatable in a socket on the frame, means for intermittently o eratingsaid slotted pinion to twist wires he d between said aws, and. means foropening said jaws, substantially as set forth.
